You're completely ignoring the efficiency aspect. ICEs simply cannot compete with EVs when operating at low and variable speeds: the EV will get far better overall energy efficiency. Sure, you can get a lot of torque from a diesel engine by gearing it down, but you're just not going to get very good efficiency when it's constantly braking and accelerating at low speeds. And electric motors develop peak torque at stall; ICEs always have to use clutches or torque convertors to avoid a stall, and their peak torque is very high in the rev range, so you need an even bigger engine when operating at low speeds primarily. There's only one deficiency with EVs compared to ICEs, and that's energy storage. On every other metric, they easily win.
